Hi

I have a bunch of text fields that display numbers such as 2745345

What i want is a neat bit of code that quickly and simply converts this to 2,745,345

This makes the numbers more easy to read and interpret.

Has anyone got a neat way of doing this?

Any help most gratefuly received

Cheers

John 🙂

:sigh:

luv those string manipulations…

```auto

Number.prototype.addCommas = function(n){
	n = this.toString();
	var l = n.length;
	var a = [];
	while((l-=3)>0){
		a.unshift(n.substr(l,3));
	}
	a.unshift(n.substr(0,3+l));
	return a.join(",");
}

n = 427453458492;
trace(n.addCommas());
// traces 427,453,458,492 (as a string)

```
